How does an unknown dating site—with the absurd intention of destroying Facebook—launch with 250,000 member profiles on its first day? Simple: It copies data directly from Facebook.

At least, that's the approach taken by two provocateurs who launched LovelyFaces.com this week, with profiles - names, locations and photos - scraped from publicly accessible Facebook pages. The site categorizes these unwitting volunteers into personality types, using a facial recognition algorithm, so you can search for someone in your general area who is "easy going," "smug" or "sly."

In what seems to be liberal-arts-grad-schoolese, Paolo Cirio, a media artist, and Alessandro Ludovic, media critic and editor in chief of Neural magazine, explain why they made the site.

"Facebook, an endlessly cool place for so many people, becomes at the same time a goldmine for identity theft and dating - unfortunately, without the user's control. But that's the very nature of Facebook and social media in general. If we start to play with the concepts of identity theft and dating, we should be able to unveil how fragile a virtual identity given to a proprietary platform can be."

And, the duo speculate, if people pull hard enough on that bothersome thread, Facebook's $50 billion valuation will unravel.

Facebook, as you might expect, is not amused.

"Scraping people's information violates our terms," said Barry Schnitt, Facebook's director of policy communications. "We have taken, and will continue to take, aggressive legal action against organizations that violate these terms. We're investigating this site and will take appropriate action."

Cirio and Ludovic say they will take down a user's profile, if a person asks and the site doesn't have any indication they are actually trying to make any money. Instead, it's part of a series of prank sites, the first two of which aimed at Google and Amazon, intended to make people think more about data in the age of internet behemoths.

Moreover, it's a bit funny hearing Facebook complain about scraping of personal data that is quasi-public.

Mark Zuckerberg, the company's founder, made his name at Harvard in 2003 by scraping the names and photos of fellow classmates off school servers to feed a system called FaceMash. With the photos, Zuckerberg created a controversial system that pitted one co-ed against another, by allowing others to vote on which one was better looking.

So even if Facebook's anticipated legal nasty gram makes its way to the duo, who seem to be based somewhere in Europe, they'll have an excellent defense.
